VAPOR-BURNER.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed March 3, 1906. Serial No. 248,261.

My invention relates to improvements in incandescent vapor -burninglamps; and it consists in the features of construction here inafterdescribed and claimed.

In the drawings forming part of this speciflcation, Figure 1 representsa side elevation, Fig. 2 a vertical section, and Fig. 3 a plan view, ofmy invention. Fig. 4 represents a plan view similar to Fig. 3, certainof the parts being omitted for clearness of illustration. Fig. 5represents a section on line as a; of Fig. 4. Fig. 6 represents asection on line y y of Fig. 1. Fig. 7 represents a plan view Fig; 8represents a section on line 2 z of Fig. 7. Fig. 9 represents a verticalsectional view of the mixingtube in detached position, the section beingtaken on line 00 0c of Fig. 10; and Fig. 10 represents a plan view ofFig. 9.

Referring to the drawings, 1 designates the frame of the lamp, to whichthe supply-pipe 2 is secured, as by means of the set-screw 3.

4 designates a valve casing which leads downwardly {into the laterallyextending vaporizing-pipe 5, leading to the vaporizingchamber 6. Thevapor-tube 7, leading from the chamber 6, terminates in the tip 8, overwhich is the mixing-tube 9, having its lower open end 10 chamfered orflaring. The upper end of the tube 9 is threaded into the plate 11,constituting the bottom of the casing 12 of the mixing-chamber 13.

14 designates a deflector located in the mixing-chamber 13, comprisingan annular ring 15, a conical base 16, and ribs 17, outwardly concave,connecting the ring 15 with the base 16, leaving intermediate slottedopenings 18. The deflector 14 is held in position in the chamber 13,asby means of an arm 19, having a laterally-extending portion restingupon the disk 11.

Above the mixing-chamber 13 is the burnerchamber 21, having the gauzeoutlet 22.

24 designates a lateral port covered by gauze 23, connecting the chamber13 with the tube 25, which is provided with a series of perforations 26,arranged underneath the tube 5 and having its end 27 contracted to forma flattened or slitted vent directed toward the tube '7 at about thepoint 29.

designates a slot or opening in the wall 12 above the openings 26 andpreferably inclined.

31 is a thin asbestos lining for the tube 5, filled near its outer endwith suitable porous material 32.

The operation is as follows: The hydrocarbon flows by gravity throughthe pipe 2,

valve-casing 4, pipe 5, chamber 6, tube 7, be-

ing vaporized in its passage, the vapor issuing from the tip 8 andentering the mixingtube 9 with atmospheric air, thence passing to thechamber 13. The commingled vapor and air are deflected by the base 16and ribs 17 of the deflector 14, passing through the slits 18 into thechamber 21. Thence they pass to the burner and are ignited. A smallportion passes through the gauze 23, port 24, and tube 25, issuingthrough and being ignited at the ports 26, the flame impinging upon theunder side of the tube 5, part also issuing through'and burning at theorifice 27, so that the flame impinges against the tube 7, therebyheating both the tubes 5 and 7 to vaporize the contained hydrocarbon.Vapor also issues from the slit 30 and is ignited by the flame at themantle, serving to relight the vapor at the openings 26 and 27 shouldthe same be accidentally extinguished.

For convenience the more important parts of my invention may also bedefined as follows: the pipe 5 and chamber 6 as the vaporizer, the tube7 as a vapor-tube, the pipe 9 as the mixing-tube, the chamber 13 as themixing-chamber, the openings 26 and 27 as vaporizing-burners, and theport 30 as the pilot-burner.

I claim 1. In a burner of the class described, a vaporizer, a1nixing-chamber, a mixing-tube leading to said mixing-chamber, avaportube leading from said vaporizer to said mixing-tube, a spreadingdevice in said mixingchamber, a superposed burner-chamber and burner, avaporizing-burner adjacent said vaporizer, anda pilot-burner above saidvaporizing-burner, both said burners being connected with saidmixing-chamber.

2.' In a vapor-burner, a supply-pipe, a vapor tube leading therefrom andprovided with an outlet, a commingling-tube located above said outlet, aspreading and deflecting chamber into which said commingling-tubedischarges, a spreader contained in said chamber, a port leading fromsaid chamber, a gauze covering for said port and a gas-tube extendinglaterally and partly around the exterior of said chamber and providedwith a series of ports in its upper portion, and an elongated orificedischarging against said vapor-tube.

3. In a vapor-burner, a supply-pipe, a vapor-tube leading therefrom andprovided with an outlet, a commingling-tube located above said outlet, aspreading and deflecting chamber into which said cornmingling-tubedischarges, a spreader contained in said chamber, a port leading fromsaid chamber, a gauze covering for said port and a gas-tube extendinglaterally and partly around the exterior of said chamber and providedwith a series of ports in its upper portion, and an elongated orificedischarging against said vaportube in combination with a relightingdevice.

4. In a vapor-burner, a supply-pipe, a va por-tube leading therefromprovided with an outlet, a commingling-tube located above said outlet, aspreading and deflecting chamber into which said coinmingling-tubedischarges, a spreader contained in said chamber, a port leading fromsaid chamber, gauze covering said port and a gas-tube extendinglaterally and partly around said chamber, and provided with a series ofports in its upper portion, and an elongated orifice discharging againstsaid vapor tube, said spreader consisting of a ring having a baseportion of less diameter and ribs joining said ring and base portion.

5. In a vapor-burner, a supply-pipe, a vapor-tube leading therefrom andprovided with an outlet, a commingling-tube located above said outlet, aspreading and deflecting chamber into which said commingling-tubedischarges, a spreader contained in said chamber, a port leading fromsaid chamber, gauze covering said port and a gas-tube extendinglaterally partly around said chamber and provided with a series of portsin its upper portion, and an elongated orifice discharging against saidvapor tube, said spreader consisting of a ring having a base portion ofless diameter and concave ribs joining said ring and base portion, saidvaportube having a flaring mouth and being secured to a base in threadedengagement with the lower walls of said spreading and deflectingchamber.

In witness whereof I have hereunto set my hand, at the city ofPhiladelphia, this 23d day of February, 1905.
